Rails: call another controller action from a controller

Question

I need to call the create action in controller A, from controller B.

The reason is that I need to redirect differently when I\'m calling from controller B.

Answer 1

This is bad practice to call another controller action.

You should

1. duplicate this action in your controller B, or
2. wrap it as a model method, that will be shared to all controllers, or
3. you can extend this action in controller A.

My opinion:

1. First approach is not DRY but it is still better than calling for another action.
2. Second approach is good and flexible.

3. Third approach is what I used to do often. So I'll show little example.

   def create
     @my_obj = MyModel.new(params[:my_model])
     if @my_obj.save
       redirect_to params[:redirect_to] || some_default_path
      end
   end
   

So you can send to this action redirect_to param, which can be any path you want.
